About Coldlar

Founded in 2017, Coldlar, also known as Beijing KUSHEN Information Technology Co. Ltd., is a private company operating from Haidian, China, specializing in security solutions for blockchain digital assets. The company was established by a team including Dawei Yuan, who previously co-founded the cryptocurrency exchange Huobi.com. This background in digital currency exchange likely provided the founding team with firsthand insight into the security vulnerabilities and asset protection needs within the burgeoning crypto market.

Coldlar's business is centered on providing secure storage for a wide range of cryptocurrencies for individuals and institutions, including high-net-worth clients. The company generates revenue through the sale of its hardware wallet products. The core of Coldlar's offering is a two-part system: a physical hardware device (the cold wallet) and a companion mobile application (the hot wallet). This "cold-heat isolation" architecture is designed to keep users' private keys entirely offline, eliminating exposure to internet-based threats and hacking attempts.

The hardware wallet itself is a physical device, completely disconnected from any network, used for creating and signing transactions. Transaction information is transferred between the hardware and the mobile app via encrypted QR codes or Near Field Communication (NFC), ensuring that the private keys are never online. The companion app is used for more convenient tasks like checking account balances and broadcasting the already signed transactions to the blockchain network. Coldlar's product lineup includes various models such as the Pro series, the card-like Touch, and the flagship Ultra, which cater to different user needs from portability to advanced portfolio management. These devices often feature a full-screen display, fingerprint scanners, and are built with materials like high-strength alloy frames. Security is further bolstered by the use of military-grade CCEAL6+ certified security chips to protect against physical tampering and side-channel attacks.
